Ignition Coil & Iridium Spark Plugs for Land Rover Range Rover (2010-2012) 5.0L V8

High-Output Ignition Coil & Iridium Spark Plugs for 2010-2012 Jaguar XF

Replaces degraded factory ignition components to restore proper combustion, eliminate misfires, and improve spark efficiency on the AJ133 5.0L V8.

The Stock X250 Ignition Weakness

As the AJ133 5.0L V8 accrues mileage, factory ignition coils suffer from thermal degradation. Positioned directly above the cylinder heads, these coils endure extreme heat soak cycles. Over time, internal epoxy and secondary windings break down, causing increased electrical resistance and ignition misfires. This weak combustion translates to rough idling, hesitation under heavy throttle, and premature plug fouling. Furthermore, standard OEM plugs erode naturally over time, increasing the spark gap and forcing aging coils to work harder, which drastically compounds drivability issues under load.

The Engineering Solution

This OEM-grade ignition coil and Iridium spark plug package provides a comprehensive ignition system refresh. The upgraded coils feature heavy-duty copper wire windings engineered to lower internal resistance and maximize voltage output. This ensures a more consistent spark under high loads and RPMs. The coil housings are constructed from heat-resistant thermoplastics to withstand prolonged engine bay temperatures, preventing the cracking and arcing that plagues aging factory units. Paired with precise Iridium spark plugs featuring a fine-wire center electrode, this kit requires less primary voltage to generate a spark while delivering superior energy transfer. The iridium tips resist arc erosion, ensuring the spark gap remains precisely calibrated over tens of thousands of miles.
